Datura wrightii or Sacred Datura is the name of a poisonous perennial plant and ornamental flower of southwestern North America. It is sometimes used as a hallucinogen. Datura wrightii is classified as a deliriant and an anticholinergic.
It is a vigorous herbaceous perennial that grows 30 cm to 1.5 m tall and wide. The leaves are broad and rounded at the base, tapering to a point, often with wavy margins. The flowers are the most striking feature, being sweetly fragrant white trumpets up to 20 cm (8 inches) long, often tinted purple, especially at the margin. In clear weather, flowers open at nearly full dark and wither a few hours after sunrise the following morning; in cloudy weather, they may open earlier and last longer.
Datura wrightii is found in northern Mexico and the adjoining U. S. states, as far north as southern Utah, in open land with well-drained soils. It is also commonly planted as an ornamental, especially in xeriscapes.
The name commemorates the botanist Charles Wright.

|Germination||Short cold moist stratification recommended, but not required.<br /> 1. Fill the planting flat with potting soil. Moisten the soil, but make sure it is still loose. Keep the soil at the same moisture level until the seeds sprout.<br /> 2. Plant the Datura seeds in the planting flat just under the surface, about an eighth of an inch deep. Pat the soil lightly with the palm of your hand after planting the seeds.<br /> 3. Place the flat in a warm spot until the seeds germinate. They will germinate in two to four weeks. Once the seedlings sprout, place them in a location with natural light or direct sun. They will do best over the winter if they are not over watered.<br /> 4. Transplant the young plants outside when there is no danger of a frost. Choose a sunny location with soil that drains well. Carefully separate each plant to minimise root damage. Each plant can grow up to 6 feet wide, so leave about 4 to 6 feet between each plant if you transplant them to a planting bed. If you transplant them to a pot, one plant will fill a large pot as it matures.<br /> 5. Gather the seeds from the new plants at the end of the growing season if you want to plant more plants for yourself or share them with friends. If you don't gather the seedpods, the seeds that fall will often sprout in the spring. If you want to preserve these seedlings, transplant them to a pot or location where they will have plenty of room to grow.<br /> Info source: eHow.co.uk|
